Re: mom of 3rd grader with autism and 3 typical children (tgrlisa)

I find it curious that your son learned multiplication before addition, since multiplication is just a generalization of addition, so there may be a lack of understanding. I'm also considered a 'high functioning autistic' so I would be glad to help as much as I can.

Here gives the list of properties in the real number system. Properties of Addition
Personally I found visual cues rather than english clues a better indicator, but I'm not closed to the idea of other methods.

ex. Suppose you wanted to explain commutivity. ex. 3 + 5 = 5 + 3. have your 3rd grader draw three circles, then five. then count how many there are. do the same but have him draw five circles first and then three and count how many there are. notice they are the same number / 'picture'

Re: mom of 3rd grader with autism and 3 typical children (tgrlisa)

it was really the rhyming system that got him to remember the multiplication facts. They think he also has a math disability. I don't think he really understands the properties of multiplication. he was just able to remember the rhymes for the facts. that is why I am looking for a rhyming system for addition. we can't get past the plus ones. Thanks for your suggestion. It is much appreciated

ah, words that sound the same for results. shoe almost sounds like two, etc. the problem with this is that given a new arbitrary problem he won't know what to do.

has he seen something like this before? It's visual too, but I suppose at the headings you could have drawings of things. ex. above the two have a picture of a shoe if that really would help. I also found that a speech therapist helped a lot with my development for learning in general.

When you move one cell to the right on a row, you are adding, so maybe try to derive this table?
